COKE-OVEN STRUCTURE.

Specification or Letters Patent. Patented Jan. 24, 1,922.

Application filed January 26, 1920. Serial No. 354,176.

Tol al?, whom t may concern:

Be it known that I, JOSEPH BECKER, a citizen of the United States, residing in Pitts burgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Coke-Oven Structures, of which the following is a specification.

This invention relates generally to coke oven structures and has for its essential object the provision of individual protective covers for the individual jamb bricks, of which are constructed the jambs that face the end of the heating walls of the oven battery. The jambs are often exposed to jars, blows and other rough usage, in the operation of the coke oven doors, and from other causes; the invention not only effectively protects the jambs against damage but also leaves the joints, between the individual jamb bricks, readily accessible so that these joints may be pointed up, whenever necessary, without removing the coverings from the jamb bricks.

The inventionv includes amo-ng its objects such other improvements or advantages in construction and operation as are found to obtain in the structures and devices hereinafter described or claimed.

In the accompanying drawings, forming a part of this specification, and showing for the purpose of exempliication, a preferred form and manner in which the invention may be embodied and practiced, and without limiting the claims of the invention specifically to such illustrative instance or instances :m

Figure 1 is al fragmentary side elevation of a coke oven structure provided with the improvements of the present invention.

Figure 2 is a horizontal sectional View of the same, taken in a plane indicated by the line 22 of Figurel.

Figure 3 is a top plan view of a jamb brick employed in the construction of the jambs at the end of a heating wall and showing a fragmentary horizontal section of the coke oven door co-operating therewith.

Figure -l is a front elevation of a number of jamb bricks, such as illustrated in Figure 3.

Figure 5 is a vertical sectional elevation taken in a plane indicated by the line 5--5 of Figure 4.

Figure 6 is a top plan view of the jamb bricks employed in the construction of that portion of the jambs where the peep-hole is located.

Figure 7 is a front elevation of the construction illustrated in Figure 6.

ihe same characters of reference indicate the same parts throughout the several views. n In its present embodiment, the invention is incorporated in a coke oven battery of the by-product type, and for convenience the present description will be confined to this use of the invention. The features of the invention are, however, readily susceptible of other uses, for example, in connection with coke oven batteries of other form; hence, it is manifest that the scope ofthe invention is by no means confined to the speciiic use and specific embodiment herein described.

Referring to the drawings:

There is shown a fragment of a coke oven battery of the by-product type, which embodies in its construction a plurality of coking chambers 11 arranged side by side, and having the usual crosswise extending alternating heat-ing walls 12 intermediate adjacent coking` chambers, as shown in Figure 2, said heating walls being provided with the usual vertical flame-fines 13 for generating heat to coke the charges of coal in the coking chambers 11. The heating walls 12 extend vertically to the top 14 of the coke oven battery, said top being of the usual construction, and facing the end of each heating wall l2 is aijamb l5 consisting essentially of a vertical wall section ysubstantially co-extending along the end of the heating wall and formed of jamb bricks, as will be hereinafter described. The outer face of each jamb 15 is braced by a pair of vertical buckstays 16 which extend vertically beyond the top 14 of the coke oven battery. As stated, the heating walls 12 extend crosswise of the coke oven battery and their opposite ends are also placed with jambs such as are indicated at 15, and vertical buekstays are also provided for bracing the outer faces of the jambs on that side of the battery opposite to that indicated on the drawing.

In accordance with the usual practice, the heating walls 12 are constructed of linerbrick, sections 16 and 17, connected together at intervals by tie-brick sections 18, and the ame-flues 13 are located between the several tie-brick sections, as shown. The several sections constituting each heating wall are constructed of vsilica brick. whereas the jambs`l5"facing the ends of the heating wall are constructed of clay bricks. As a result of the facts that the heating walls and the adjoining jambs are formed of materials having different co-efiicients of expansion, that the jambs are exposed `exteriorly Vto radiation and that the buckstays exert variable? pressures upon the amb bricks during expansion or contraction of the battery, thejoints between 'theseveral bricks forming a jamb frequently open up. so that it is necessary to point up these joints in order to-.preserve gas-tight conditions at the end of each heating wall.

The. mouth of veach coking chamber is closed lby a coke oven door 19 consisting essentially of a metallic outer shell 20 and the usual internal refractory lining 21 supported byfsaid outer shell. As shown in Figs. 2and 8, the outer shell 2O is formed with opposite vertically' extending shoulders 22 2adapted to rest against the reverse shoulders 28 'of the j ambs at the opposite sides of the mouth of the coking chamber. `W hen in closed position, the door 19 projects within the coking chamber l1 beyond the shoulders 28' of thel jambs; and when a charge in a coking chamber'has been coked the doors of Such chamber are opened or removed and the finished coke is pushed out of the cham'- ber iand disposed of in the usual way. The operationof removing and replacing the doors is necessary every time a charge of coal has been coked in a coking chamber, and this operation is frequently liable `to cause damage tothe jamb bricks by knocking 'of the door against them when removing or replacing the door.

According to the present invention, individual protective covers are provided with the individual jamb bricks of each jamb, wherebytthe jambs are not only protected from damage but the joints between the bricks may also be reached whenever it becomes necessary to point up these joints, without removing the covers. Each j amb is constructed mainlyi of a plurality of bricks 24 of thegeneral form illustrated in Figs. 8 'to 5 inclusive, said bricks respectively having vertically-extending shoulders 25 formed in theiriopposite side faces and a continuous horizontal groove 26 extending around theI frontface 27 of and connecting the shoulfder 25` on the opposite sides of each brick. The bricks 24 are laid one upon the other to form the j amb, and the horizontal joints between them are filled with a suitable binding material. At thetier of eachjamb where the peep-hole 28, for inspecting the Ihorizontal fiue of the heating wall, is located. two companion jamb bricks 29are employed instead of one. The outside faces 8O of the jamb bricks 29 are similar to the analogous coke oven door.

faces of a jamb brick 24 and each brick is provided with aV continuous horizontal groove 81 extending from the shoulder 25 of the outside face 80 around the front face and terminating at a vertical groove 88 located at the junction of the front face 82 and the inside face 84 of each brick '29. As shown in Figs. 6 and 7, the inside faces 84 of the pair of bricks 29 are spaced from each other and between them is positioned a filler brick 85 lower in height than the j amb bricks 29 to leave/the peep-hole 2S which extends through the jarnb. The vertical joints between the jamb bricks 29 and the filler brick S55-are filled with a suitable binder, as well as the horizontal joints between the three bricks just mentioned and the amb brick 24 beneath them. Each of the jamb bricks 24 is protected by a cover 86, preferably formed of metal, and having wings 87 extending from the front face ofthe cover along the side faces of kthe j amb brick. At their inner ends the wings 87 of the cover are provided with shoulders 88 tting the companion sh`oulders'25 of a amb brick; and projecting from the inner faces of the plate 86 is a continuous horizontal tongue 89 that enters the groove 26 of the jamb brick to hold the cover firmly in place on the front and side faces of the'jamb brick. The jamb bricks 29 are also provided with covers 40 extending over theirfront and outside faces, said cover having shoulders 41 fitting with shoulder 25 of the jamb bricks 29 and a continuous tongue 42 that enters the groove 81 of the jamb bricks `29. At their ends adjacent to the vertical grooves 88 the covers 40 are provided with vertical flanges 48 which enter said grooves.

.Vith the above construction the individual j amb bricks constituting a jamb 15 are adequately protected by individual covers eX- tending over their front and side faces, so that damage to the jamb bricks from any cause is to a large extent eliminated. The shoulders 88 of the amb brick covers 86 and the analogous shoulders 41 of the amb brick covers 40 constitute the vertical shoulder23 of the jamb, that receives the impact of the The joints between the bricks are at all times accessible and may be maintained in Aperfect condition without removing a single cover from a j amb brick.

The invention as hereinabove set forth is embodied in a particular form of construction but may be variously embodied within the scope of the claims hereinafter made.
